WALTER WHEAL, 0F WORCESTER, ENGLAND, ASSIGNOR TO HEENAN & FROUDELIMITED, OF MANCHESTER, ENGLAND.

MATCH-MAKING- MACHINE.

Application filed May l5, 1917.

To all 'whom t may concer-n:

Be it known that I, WALTER Wma-i1., a British subject, residing atIVorcester, county of Worcester, England, have invented certain new anduseful Improvements in or Relating to Match-Making Machines, of whichthe following is a specification.

This invention relates to machines in Which matches are'made by dippingthe match stalks into an igniting composition in a trough or container.

In these machines it is desirable to maintain a lovv temperature, as arise of temperature is detrimental to the igniting composition Whiledrying or solidifying.

The invention consists in incasing the drums and traveling bands of themachine and connecting the interior of the machine to an air cooler bysuitable ducts through which cooled air is forced into the body of themachine and to the revolving cylinder or drum which carries thetraveling` belt so that the cooled air is caused to have a coolingaction on the dipping trough and the stored composition therein, thusmaintaining the composition in the dipping trough and the interior ofthe machine at a low temperature.

The invention Will be fully described with reference to the accompanyingdrawings.

Figure 1 is a side elevation, partly in section, illustrating anembodiment of my invention.

Fig. 2 is a plan View of the machine.

The match machine is of ordinary construction vvith a rotary drum orcylinder A and endless band B by which the matches are carried, adipping trough C and a fan E which supplies air to the interior of thecasing. The particular structure of the drum or cylinder A, the endlessband B. the dipping trough C, and/ian E is not controlling as to thefeatures of the invention and may be varied in accordance withWell-known match machine structures embodying an endless band Jfor anobvious purpose.

According' to the invention the drum A .and traveling band B are incasedby a suitable covering or casingr H. The covering or casing H isair-tight. except Where an air outlet opening hereinafter specied islocated, so that cold air mav be caused to eii'ectually perform itscooling function Specification of Letters Patent.

Serial No. 168,796.

relat'vely tothe composition applied to the natch tips. Upon the top ofthe machine, a rotary cooler D and a fan E adjacent thereto are mounted,the cooler being of the prei'erred type shown and described in Il. S.Patents Nos. 1,018,242 and 1,018,243, said air cooler having ducts d (Zcl2 leading therefrom to supply cold air to the interior of the cylinderof the machine.

The air is forced by the fan E into the body of the machine by Way ofthe ducts (Z and CZ through the fan E which is provided to assist fan Ein its function of distributing the air, and into the interior of therevolving cylinder A or by Way of the branch duct cl2 direct from therotary cooler D, in the latter case the fan E not functioiiing. Dampers(Z3 are placed in the ducts to control the circulation of the cold airand in the rear of the cylinder A a partition a is mounted to controland direct the currents of cold air. It Will noW be clear that if thedamper Z3 in the duct d is closed. cool air will still be supplied bythe fan E to the interior of the drum A by Way of the duct d2. theoutlet from which is in close proximity to the open end of the drum A.It the damper cl3 in the duct cl2 closed, the air will be supplied bythe 'fan E by Way of the ducts CZ and d and fan E to the interior of thecasing. In either case, the air will escape through the outlet F.

Cold air is thus forced into the machine over the traveling band B. intothe cylinder A and over the surface of the stored composition andescaping through an aperture F adjacent to the dipping trough, andmaintains the composition throughout the machine at a low temperature.

What I claim as my invention and desire to protect by Letters Patent is:k

The combination with a match making machine involving drum,travelingband, and a dipping trough containinga composition forapplication to match sticks, of a casing forming an air-tight inclosurefor the match making mechanism, an air cooler mounted on the top of oneextremity of the casing. a fan on the top of the opposite extremity ofthe casing for drawing air from the cooler and supplying it to themachine, ducts between the cooler and fan and connected to the interiorof the machine adjacent to the drum. and a partition Within the casingin rear of the drum and adjacent to tho dipping tough, the casing havingan outlet at one Side close to the partition and whereby theV ColdCurrents 0I" air will be folcod into the machine over the traveling bandvand into the Cylinder and also over the surface' of the composition inthe dipping trough mld escapo through the outlet adjacent to the trough.
